Application filed March 17,

To all whom it may concern:

Be it known that 1, ANDREW BAKER, a citizen of the United States, and a resident of Spring Valley, in the county of Rockland and State of New York, have invented a new and Improved Cleaner Attachment for Silk-' Throwing hfachines, of which the following is a full, clear, and exact description.

My invention is particularly intended for use on a silk-throwing machine to remove from the silk threads the bunches of waste or like particles adhering to the threads. 7

Objects of the invention are toprovide a cleaner attachment, adapted to be secured to the cross piece running through the silkthrowing machine below the upper bobbins, and provided with combs disposed horizontally, transverse to the path of movement of the threads; and to provide a cleanerattachment having a comb so formed as vto avoid all danger of the breaking of the silk threads, except when a bunch of waste or the like is twisted fast in the thread.

The nature of the attachment and its ad- .vantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming part of this specificaform, includes a cross piece A running through the vertical members B of the frame below the upper bobbins 0, between the same and the usual drop eyes D, through which the silk threads E run, said threads running also over the rollers F to the lower bobbins G. My improved attachment designated generally by the numeral 10 is adapted to be secured to the cross piece A transversely thereof, the under side of the central body portion of the attachment having a depression to receive the top of said cross piece. The attachment is secured in position by any suitable means, such as bolts llhaving nuts 12, the bolts passing through bolt holes 13 in the attachment.

combs being received in rabbets 15 formed in the ends of the body of the attachment. The arrangement is such that the combs 14 will project at each side of the machine beyond the cross piece .A and'in the path of the threads E so that the said threads will be caused to pass through the combs between the teeth thereof. 7

Each comb includes resilient metal teeth 16, the teeth being produced separately in the form of flat metal strips. The teeth are disposed vertically between side fingers 17. To uniformly space the teeth a fine wire 18 is laced over upper and lower pairs of cross bars 19 on the teeth and between said teeth.

The wire 18 and cross bars 19 are applied to, the teeth a distance in front of the rear ends of the teeth, that is to say, adjacent to the ends of the rabbets 15 in which theteeth are received. The numeral 20 indicates solder, a part of which is broken away in Fig. 4, the solder, in practice, being applied to the teeth from the rear ends to the front transversebars 19 so as to unite the whole. Rearward of the wire 18 and bars 19. top and bottom plates 21 are applied to the teeth and these may be held in position by the solder 20 so that the comb will be in the form of a unitary structure made solid at the inner end thereof. To removably secure the combs in position bolts 22 are employed having nuts 23. With a comb thus formed the teeth will accommodate the threads E between the opposed flat sides of the teeth and will engage the same in a manner to remove any adhering particles without damage or danger of breaking the threads, except when a bunch of waste or the like is twisted fast in the thread.

I wish to statein conclusion that although the illustrated example constitutes a practical embodiment. of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same. can be considerably varied without departurefrom the spirit of the invention as defined in the appended claims.

Having thus described my invention, I

claim as new, and desire to secure by Letters .Patent: 7

1. The combination with a silk-throwing machine, having a cross piece running through the throwing machine below the up- .per bobbin spindles, of a cleaner attachment having a member secured to said cross piece, and having laterally projecting end combs horizontally disposed beyond. the said cross bar at the sides of the machine, in the path of movement of the silk threads.

2. A cleaner attachment for silk-throwing machines and the like, including a comb, a support carrying said comb, and means to secure the support to the machine, said comb 10 comprising teeth each formed of a fiat resilient metal strip, cross bars on the flattened teeth at the upper and lower sides thereof, spacing Wires laced about the said transverse bars and between the'teeth, upper and lower plates on the teeth at the base thereof rearward of the Wires and cross bars, and means uniting all the said elements of the comb together.
